Problems solved by technology

However, the current lamps cannot meet the long-term use, and must be maintained regularly, which is time-consuming and labor-intensive, and it is necessary to ensure sufficient power resource supply
Therefore, it often occurs that tunnel lighting is out of control due to damage to lamps or insufficient power supply, causing major traffic accidents

Abstract

The invention discloses a sunlight lighting optical system for a tunnel portal. The sunlight lighting optical system comprises a solar tracking device, a parabolic reflector installed on the solar tracking device, a collimating lens installed at the coaxial and confocal position of the parabolic reflector, a reflection plate fixedly installed at the emergent light end of the collimating lens and a light guide tube installed on a tunnel wall. An inlet of the light guide tube is arranged at the position connected with outgoing beams of the reflection plate, semi-reflection semi-transparent mirrors are arranged in the light guide tube at intervals, reflection faces of the semi-reflection semi-transparent mirrors face to the direction of a road surface, a light outlet is formed at the position below the semi-reflection semi-transparent mirrors and on the light guide tube, a scatterer for scattering light beams reflected by the semi-reflection semi-transparent mirrors to the road surface is installed at the position of the light outlet, a full reflection mirror is arranged at the tail end of the light guide tube. The sunlight lighting optical system lights a tunnel through a solar lighting system, accordingly reduces building cost of projects, saves electric power resources and better serves road management.

Description

technical field [0001] The invention belongs to the technical field of tunnel lighting, in particular to an optical system for lighting a tunnel entrance with sunlight. Background technique [0002] With the rapid development of the economy, my country's electricity demand is growing at a rate of more than 20% per year. According to the current economic development trend and China's resource situation, there will be tension in power supply after 2010. With the rapid development of road traffic in our country, the number of road tunnels is also increasing day by day. The state stipulates that road tunnels with a length of more than 400m must be equipped with lighting systems. At present, high-voltage Xe lamps, or LED lamps and other lamps are most used in tunnel lighting. Due to the complex terrain and relatively long mileage of many tunnels, the requirements for power consumption and lamp life are very high. However, the current lamps cannot meet the long-term use, and must...
